Greetings. I'm looking for help in attaching a synch cord so that I can use an electronic flash on my Speed. The lens is a 135mm Graphex with two prongs for the electrical connection.

Question: What kind of cords are out there? Are there adapters that allow you to go from two-prong to a standard end, or do you have to have a dedicated cord? All my Googling and Yahooing has yielded little info., so I'm hoping someone here can sort it out for me. Thanks.

The two pins on the Graphex shutter are called a Bi post connector.
Hot shoe flash sockets are called PC.
Some handle mount flashes use a two blade socket that takes a plug similar to common electrical plugs and are called Household. Studio strobes may use 1/4 inch mono plugs or 1/8 inch mono plugs.

You need a BiPost to whatever type plug the flash you wish to use requires. Check the Pro photo shops in your area as they may have what you need in stock._________________The best camera ever made is the one that YOU enjoy using and produces the image quality that satifies YOU.

electric razor power cords are reported to fit the bi post pins. I have not tried one._________________The best camera ever made is the one that YOU enjoy using and produces the image quality that satifies YOU.

Note that the Paramount bipost socket and the household plug have right-angle mounts, which is not the case with the razor cords that I've seen. For our equipment, the right-angle mounting would seem to be much preferable to a straight-out arrangement.

I stumbled across a Norelco cord that will fit. I assume a Remington cord will work also.
Cords from razors made from the late 50's through the 70's or 80's may work (cord plugs into the razor body).
I don't use razors of any kind and my trimmer charging cord definitely will not work._________________The best camera ever made is the one that YOU enjoy using and produces the image quality that satifies YOU.
